5 km = 3 miles
0.3 cm = 0.12 in

Answer:
r = 0.728 m
Explanation:
The intensity is defined as the ratio between the power per unit area
I = P / A
Where A is the area of the sphere where the wave is
A = 4π r²
In this exercise we are given the power of the P = 10.0 W micro waves, the safe intensity I₁ = 1.5 W / m²
A₁ = P / I₁
Calculate
A₁ = 10.0 / 1.5
A₁ = 6.6667 m²
Let's clear the radius of the sphere
r = √ A / 4π
r = √ (6.6667 / 4π)
r = 0.728 m
